Definitions
- the invention relates to novel 2-Heteroarylcarbonklareamide, processes for their preparation and their use for the preparation of medicaments for the treatment and / or prophylaxis of diseases and to improve the perception, concentration performance, learning performance and / or memory.
- Nicotinic acetylcholine receptors form a large family of ion channels that are activated by the endogenous messenger acetylcholine (Galzi et al., Neuropharmacol., 1995 , 34 , 563-582).
- a functional nAChR consists of five subunits that may be different (certain combinations of ⁇ 1-9 and ⁇ 1-4, ⁇ , ⁇ , ⁇ subunits) or identical ( ⁇ 7-9). This results in the formation of a variety of subtypes that exhibit differential distribution in the musculature, the nervous system, and other organs (McGehee et al., Annu., Rev. Physiol., 1995 , 57, 521-546).
- nAChR Activation of nAChR results in the influx of cations into the cell and the stimulation of nerve or muscle cells. Selective activation of individual nAChR subtypes restricts this stimulation to the cell types that have the appropriate subtype, thus avoiding unwanted side effects, such as the stimulation of nAChR in the musculature.
- Nicotinic acetylcholine receptors of the alpha7 subtype have a particularly high concentration in learning and memory brain regions, such as the hippocampus and the cerebral cortex (Séguéla et al., J. Neurosci., 1993 , 13 , 596-604).
- the ⁇ 7 nAChR has a particularly high permeability to calcium ions, increases glutamatergic neurotransmission, affects the growth of neurites and thus modulates neuronal plasticity (Broide et al., Mol. Neurobiol. 1999 , 20, 1-16).

- the P2 pellet is suspended twice in binding buffer (50mM Tris-HCl, 1mM MgCl 2 , 120mM NaCl, 5mM KCl, 2mM CaCl 2 , pH 7.4) and the suspension is centrifuged (15,000 xg, 4 ° C, 30 min).
- binding buffer 50mM Tris-HCl, 1mM MgCl 2 , 120mM NaCl, 5mM KCl, 2mM CaCl 2 , pH 7.4
- the residue is resuspended in binding buffer and in a volume of 250 ⁇ l (membrane protein amount 0.1-0.5 mg) in the presence of 1-5 nM [ 3 H] -methyllycaconitine 0.1% (w / v) BSA (bovine serum albumin) and various concentrations of the test substance for Incubated at 21 ° C for 2.5 h.

- the Object Recognition Test is a memory test. It measures the ability of rats (and mice) to distinguish between known and unknown objects.
- a rat In a first pass, a rat is confronted with two identical objects in an otherwise empty, larger observation arena. The rat will examine both objects extensively, ie sniff and touch. In a second round, after a waiting period of 24 hours, the rat is again placed in the observation arena. Now one of the known objects is replaced by a new, unknown object. When a rat recognizes the known object, it will first of all examine the unknown object. After 24 hours, however, a rat has usually forgotten which object it has already examined in the first pass, and will therefore inspect both objects equally. The administration of a substance with a learning and memory-improving effect can lead to a rat recognizing the object seen 24 hours earlier in the first pass. It will then examine the new unknown object in more detail than the one already known.
- This memory is expressed in a discrimination index.
- a zero index index means that the rat examines both objects, the old and the new, for the same length of time; ie she did not recognize the old object and reacts to both objects as if they were new.
- a discrimination index greater than zero means that the rat inspects the new object longer than the old one; ie the rat has recognized the old object.
- the social recognition test is a test for testing the learning or memory-improving effects of test substances.
- Test animals are individually placed in test cages 30 minutes prior to testing. Four minutes before the start of the test, the test animal is placed in an observation box. After this adaptation time, a juvenile animal is placed on the test animal and the time taken for the adult animal to study the juvenile animal for 2 minutes (Trial 1). All measures of clearly juvenile behavior are measured, i. Ano-genital inspection, follow-up and grooming where the adult has a distance of no more than 1 cm from the young. The juvenile animal is then removed and the adult left in his test cage (at 24 hour retention, the animal is returned to his home cage). Before or after the first test, the adult test animal is treated with test substance. Depending on the time of treatment, learning or storing the information about the cub may be affected by the substance. After a specified period of time (retention), the test is repeated (trial 2). The larger the difference between the investigation times determined in Trials 1 and 2, the better the adult animal remembers the young animal.

Abstract
Description
Die Erfindung betrifft neue 2-Heteroarylcarbonsäureamide, Verfahren zu ihrer Herstellung sowie ihre Verwendung zur Herstellung von Arzneimitteln zur Behandlung und/oder Prophylaxe von Krankheiten und zur Verbesserung der Wahrnehmung, Konzentrationsleistung, Lernleistung und/oder Gedächtnisleistung.The invention relates to novel 2-Heteroarylcarbonsäureamide, processes for their preparation and their use for the preparation of medicaments for the treatment and / or prophylaxis of diseases and to improve the perception, concentration performance, learning performance and / or memory.
Nikotinische Acetylcholin-Rezeptoren (nAChR) bilden eine große Familie von lonenkanälen, die durch den körpereigenen Botenstoff Acetylcholin aktiviert werden (Galzi et al., Neuropharmacol. 1995, 34, 563-582). Ein funktioneller nAChR besteht aus fünf Untereinheiten, die Unterschiedlich (bestimmte Kombinationen von α1-9- und β1-4,γ,δ,ε-Untereinheiten) oder identisch (α7-9) sein können. Dies führt zur Bildung einer Vielfalt von Subtypen, die eine unterschiedliche Verteilung in der Muskulatur, dem Nervensystem und anderen Organen zeigen (McGehee et al., Annu. Rev. Physiol. 1995, 57, 521-546). Aktivierung von nAChR führt zum Einstrom von Kationen in die Zelle und zur Stimulation von Nerven- oder Muskelzellen. Selektive Aktivierung einzelner nAChR-Subtypen beschränkt diese Stimulation auf die Zelltypen, die den entsprechenden Subtyp besitzen und kann so unerwünschte Nebeneffekte, wie z.B. die Stimulierung von nAChR in der Muskulatur, vermeiden. Klinische Experimente mit Nikotin und Experimente in verschiedenen Tiermodellen weisen auf eine Rolle von zentralen nikotinischen Acetylcholin-Rezeptoren bei Lern- und Gedächtnisvorgängen hin (z.B. Rezvani et al., Biol. Psychiatry 2001, 49, 258-267). Nikotinische Acetylcholinrezeptoren des alpha7-Subtyps (α7-nAChR) haben eine besonders hohe Konzentration in für Lernen und Gedächtnis wichtigen Hirnregionen, wie dem Hippocampus und dem cerebralen Cortex (Séguéla et al., J. Neurosci. 1993, 13, 596-604). Der α7-nAChR besitzt eine besonders hohe Durchlässigkeit für Calcium-Ionen, erhöht glutamaterge Neurotransmission, beeinflusst das Wachstum von Neuriten und moduliert auf diese Weise die neuronale Plastizität (Broide et al., Mol. Neurobiol. 1999, 20, 1-16).Nicotinic acetylcholine receptors (nAChR) form a large family of ion channels that are activated by the endogenous messenger acetylcholine (Galzi et al., Neuropharmacol., 1995 , 34 , 563-582). A functional nAChR consists of five subunits that may be different (certain combinations of α1-9 and β1-4, γ, δ, ε subunits) or identical (α7-9). This results in the formation of a variety of subtypes that exhibit differential distribution in the musculature, the nervous system, and other organs (McGehee et al., Annu., Rev. Physiol., 1995 , 57, 521-546). Activation of nAChR results in the influx of cations into the cell and the stimulation of nerve or muscle cells. Selective activation of individual nAChR subtypes restricts this stimulation to the cell types that have the appropriate subtype, thus avoiding unwanted side effects, such as the stimulation of nAChR in the musculature. Clinical experiments with nicotine and experiments in various animal models indicate a role of central nicotinic acetylcholine receptors in learning and memory processes (eg Rezvani et al., Biol. Psychiatry 2001 , 49, 258-267). Nicotinic acetylcholine receptors of the alpha7 subtype (α7-nAChR) have a particularly high concentration in learning and memory brain regions, such as the hippocampus and the cerebral cortex (Séguéla et al., J. Neurosci., 1993 , 13 , 596-604). The α7 nAChR has a particularly high permeability to calcium ions, increases glutamatergic neurotransmission, affects the growth of neurites and thus modulates neuronal plasticity (Broide et al., Mol. Neurobiol. 1999 , 20, 1-16).

Die Eignung der erfindungsgemäßen Verbindungen zur Behandlung von kognitiven Störungen kann in folgenden Tiermodellen gezeigt werden:The suitability of the compounds according to the invention for the treatment of cognitive disorders can be demonstrated in the following animal models:
Der Objekt-Wiedererkennungstest ist ein Gedächtnistest. Er misst die Fähigkeit von Ratten (und Mäusen), zwischen bekannten und unbekannten Objekten zu unterscheiden.The Object Recognition Test is a memory test. It measures the ability of rats (and mice) to distinguish between known and unknown objects.
Der Test ist bei Blokland et al., Neuro Report 1998, 9, 4205-4208; A. Ennaceur et al,. Behav. Brain Res. 1988, 31, 47-59; A. Ennaceur et al., Psychopharmacology 1992, 109, 321-330; und Prickaerts et al., Eur. J. Pharmacol. 1997, 337, 125-136 beschrieben.The test is in Blokland et al., Neuro Report 1998 , 9 , 4205-4208; A. Ennaceur et al. Behav. Brain Res. 1988 , 31 , 47-59; A. Ennaceur et al., Psychopharmacology 1992 , 109, 321-330; and Prickaerts et al., Eur. J. Pharmacol. 1997 , 337 , 125-136.
In einem ersten Durchgang wird eine Ratte in einer ansonsten leeren größeren Beobachtungsarena mit zwei identischen Objekten konfrontiert. Die Ratte wird beide Objekte ausgiebig untersuchen, d.h. beschnüffeln und berühren. In einem zweiten Durchgang, nach einer Wartezeit von 24 Stunden, wird die Ratte erneut in die Beobachtungsarena gesetzt. Nun ist eines der bekannten Objekte durch ein neues, unbekanntes Objekt ersetzt. Wenn eine Ratte das bekannte Objekt wiedererkennt, wird sie vor allem das unbekannte Objekt untersuchen. Nach 24 Stunden hat eine Ratte jedoch normalerweise vergessen, welches Objekt sie bereits im ersten Durchgang untersucht hat, und wird daher beide Objekte gleichstark inspektieren. Die Gabe einer Substanz mit lern- und gedächtnisverbessemder Wirkung kann dazu führen, dass eine Ratte das bereits 24 Stunden vorher im ersten Durchgang gesehene Objekt wiedererkennt. Sie wird dann das neue unbekannte Objekt ausführlicher untersuchen als das bereits bekannte. Diese Gedächtnisleistung wird in einem Diskriminationsindex ausgedrückt. Ein Diskiminationsindex von Null bedeutet, dass die Ratte beide Objekte, das alte und das neue, gleichlang untersucht; d.h. sie hat das alte Objekt nicht wiedererkannt und reagiert auf beide Objekte als wären sie neu. Ein Diskriminationsindex größer Null bedeutet, dass die Ratte das neue Objekt länger inspektiert als das alte; d.h. die Ratte hat das alte Objekt wiedererkannt.In a first pass, a rat is confronted with two identical objects in an otherwise empty, larger observation arena. The rat will examine both objects extensively, ie sniff and touch. In a second round, after a waiting period of 24 hours, the rat is again placed in the observation arena. Now one of the known objects is replaced by a new, unknown object. When a rat recognizes the known object, it will first of all examine the unknown object. After 24 hours, however, a rat has usually forgotten which object it has already examined in the first pass, and will therefore inspect both objects equally. The administration of a substance with a learning and memory-improving effect can lead to a rat recognizing the object seen 24 hours earlier in the first pass. It will then examine the new unknown object in more detail than the one already known. This memory is expressed in a discrimination index. A zero index index means that the rat examines both objects, the old and the new, for the same length of time; ie she did not recognize the old object and reacts to both objects as if they were new. A discrimination index greater than zero means that the rat inspects the new object longer than the old one; ie the rat has recognized the old object.
Der Soziale Wiedererkennungstest ist ein Test zur Prüfung der lern- oder gedächtnisverbessernden Wirkung von Testsubstanzen.The social recognition test is a test for testing the learning or memory-improving effects of test substances.
Adulte Ratten, die in Gruppen gehalten werden, werden 30 Minuten vor Testbeginn einzeln in Testkäfige gesetzt. Vier Minuten vor Testbeginn wird das Testtier in eine Beobachtungsbox gebracht. Nach dieser Adaptationszeit wird ein juveniles Tier zu dem Testtier gesetzt und 2 Minuten lang die Zeit gemessen, die das adulte Tier das juvenile Tier investigiert (Trial 1). Gemessen werden alle deutlich auf das Jungtier gerichteten Verhaltensweisen, d.h. ano-genitale Inspektion, Verfolgen sowie Fellpflege, bei denen das Alttier einen Abstand von höchstens 1 cm zu dem Jungtier hat. Danach wird das juvenile Tier herausgenommen und das adulte in seinem Testkäfig belassen (bei 24 Stunden Retention wird das Tier in seinen Heimkäfig zurückgesetzt). Vor oder nach dem ersten Test wird das adulte Testtier mit Testsubstanz behandelt. Je nach Zeitpunkt der Behandlung kann das Erlernen oder das Speichern der Information über das Jungtier durch die Substanz beeinflusst werden. Nach einem festgelegten Zeitraum (Retention) wird der Test wiederholt (Trial 2). Je größer die Differenz zwischen den in Trials 1 und 2 ermittelten Investigationszeiten, desto besser hat sich das adulte Tier an das Jungtier erinnert.Adult rats, kept in groups, are individually placed in test cages 30 minutes prior to testing. Four minutes before the start of the test, the test animal is placed in an observation box. After this adaptation time, a juvenile animal is placed on the test animal and the time taken for the adult animal to study the juvenile animal for 2 minutes (Trial 1). All measures of clearly juvenile behavior are measured, i. Ano-genital inspection, follow-up and grooming where the adult has a distance of no more than 1 cm from the young. The juvenile animal is then removed and the adult left in his test cage (at 24 hour retention, the animal is returned to his home cage). Before or after the first test, the adult test animal is treated with test substance. Depending on the time of treatment, learning or storing the information about the cub may be affected by the substance. After a specified period of time (retention), the test is repeated (trial 2). The larger the difference between the investigation times determined in Trials 1 and 2, the better the adult animal remembers the young animal.

Neben den erfindungsgemäßen Verbindungen können die pharmazeutischen Zubereitungen auch andere pharmazeutische Wirkstoffe enthalten.In addition to the compounds according to the invention, the pharmaceutical preparations may also contain other active pharmaceutical ingredients.
Die oben aufgeführten pharmazeutischen Zubereitungen können in üblicher Weise nach bekannten Methoden hergestellt werden.The above-listed pharmaceutical preparations can be prepared in a conventional manner by known methods.
Die neuen Wirkstoffe können in bekannter Weise in die üblichen Formulierungen überführt werden, wie Tabletten, Dragees, Pillen, Granulate, Aerosole, Sirupe, Emulsionen, Suspensionen und Lösungen, unter Verwendung inerter, nicht toxischer, pharmazeutisch geeigneter Trägerstoffe oder Lösungsmittel. Hierbei soll die therapeutisch wirksame Verbindung jeweils in einer Konzentration von etwa 0,5 bis 90 Gew.-% der Formulierung vorhanden sein, d.h. in Mengen, die ausreichend sind, um den angegebenen Dosierungsspielraum zu erreichen.The new active compounds can be converted in a known manner into the customary formulations, such as tablets, dragees, pills, granules, aerosols, syrups, emulsions, suspensions and solutions, using inert, non-toxic, pharmaceutically suitable excipients or solvents. Here, the therapeutically active compound should be present in each case in a concentration of about 0.5 to 90 wt .-% of the formulation, i. in amounts sufficient to achieve the stated dosage margin.
Die Formulierungen werden beispielsweise durch Verstrecken der Wirkstoffe mit Lösungsmitteln und/oder Trägerstoffen, gegebenenfalls unter Verwendung von Emulgiermitteln und/oder Dispergiermitteln, hergestellt, wobei z.B. im Fall der Benutzung von Wasser als Verdünnungsmittel gegebenenfalls organische Lösungsmittel als Hilfslösungsmittel verwendet werden können.The formulations are prepared, for example, by stretching the active ingredients with solvents and / or carriers, optionally using emulsifiers and / or dispersants, e.g. in the case of using water as the diluent, organic solvents may optionally be used as auxiliary solvents.
Die Applikation kann in üblicher Weise, vorzugsweise oral, transdermal oder parenteral, insbesondere perlingual oder intravenös, erfolgen. Sie kann aber auch durch Inhalation über Mund oder Nase, beispielsweise mit Hilfe eines Sprays, oder topisch über die Haut erfolgen.The application can be carried out in a customary manner, preferably orally, transdermally or parenterally, in particular perlingually or intravenously. But it can also be done by inhalation via the mouth or nose, for example by means of a spray, or topically via the skin.
Im Allgemeinen hat es sich als vorteilhaft erwiesen, Mengen von etwa 0,001 bis 10 mg/kg, bei oraler Anwendung vorzugsweise etwa 0,005 bis 3 mg/kg Körpergewicht zur Erzielung wirksamer Ergebnisse zu verabreichen.In general, it has been found to be beneficial to administer levels of about 0.001 to 10 mg / kg, preferably about 0.005 to 3 mg / kg of body weight when administered orally to achieve effective results.
Trotzdem kann es gegebenenfalls erforderlich sein, von den genannten Mengen abzuweichen, und zwar in Abhängigkeit vom Körpergewicht bzw. der Art des Applikationsweges, vom individuellen Verhalten gegenüber dem Medikament, der Art von dessen Formulierung und dem Zeitpunkt bzw. Intervall, zu welchen die Verabreichung erfolgt. So kann es in einigen Fällen ausreichend sein, mit weniger als der vorgenannten Mindestmenge auszukommen, während in anderen Fällen die genannte obere Grenze überschritten werden muss. Im Falle der Applikation größerer Mengen kann es empfehlenswert sein, diese in mehreren Einzelgaben über den Tag zu verteilen.Nevertheless, it may be necessary to deviate from the stated amounts, depending on the body weight or the type of administration route, the individual behavior towards the drug, the nature of its formulation and the time or interval at which it is administered , Thus, in some cases it may be sufficient to manage with less than the aforementioned minimum amount, while in other cases, the said upper limit must be exceeded. In the case of the application of larger quantities, it may be advisable to distribute these in several single doses throughout the day.
Soweit nicht anders angegeben, beziehen sich alle Mengenangaben auf GewichtsProzente. Lösungsmittelverhältnisse, Verdünnungsverhältnisse und Konzentrationsangaben von flüssig/flüssig-Lösungen beziehen sich jeweils auf das Volumen. Die Angabe "w/v" bedeutet "weight/volume" (Gewicht/Volumen). So bedeutet beispielsweise "10 % w/v": 100 ml Lösung oder Suspension enthalten 10 g Substanz.Unless otherwise stated, all amounts are by weight percent. Solvent ratios, dilution ratios and concentration data of liquid / liquid solutions are based on volume. The term "w / v" means "weight / volume".
